Corning earned $283 million, or 19 cents per share, down from $491 million, or 33 cents per share, in the same quarter last year. Excluding one-time charges, the company posted an adjusted profit of 34 cents per share for the recent quarter.

For the full year, Corning earned $1.73 billion, or $1.15 per share, down from $2.81 billion, or $1.77 per share, in 2011. Revenue rose to $8.01 billion from $7.89 billion.

Corning said that while it expects specialty materials sales to fall in the first quarter, which is typically its slowest of the year, it expects double-digit market growth for Gorilla Glass for the full year.
